PopularCampfireClientFlintSnuffedOutOfAppStore-Here'sWhy

The popular Campfire client app Flint has been removed from the App Store. Not to worry, though, because it'll be back soon, albeit minus a major feature — an omission that'll come as a result of Campfire's demotion to an all but unsupported service.
Last month, Campfire developer 37signals announced that it had rebranded as Basecamp and refocused its efforts into developing only one product, the popular project management tool of the same name. As a result, its other products, the group chat service Campfire and the contact management software Highrise, had been relegated to the sidelines.
According to Basecamp (formerly 37signals), while the exact fate of these two services is yet uncertain, they will continue to operate normally in the short term.
But Zach Waugh of Giant Comet, the developer of Flint for Mac and iOS, has taken steps with regard to the "sunsetting" of Campfire:

Since the news came out, I’ve had many people ask me what’s going to happen to Flint. To be perfectly honest, with Campfire no longer being actively developed and getting no new customers, it doesn’t make much sense to work on a Campfire client — the app store can be a tough business even for apps with strong, growing markets. From now on, Flint will only receive bug-fix updates and minor feature updates.

So, Flint should continue to work normally for as long as Campfire itself is around. But the app's iOS edition will soon have one fewer major feature: push notification support. As explained by Waugh ...

... I’m sorry to announce that I’m removing push notification support from Flint for iOS. Unlike the Mac and iOS clients, the push notification service requires a server running 24/7, being monitored and maintained. Discontinuing the push service will allow me to focus limited resources on the Mac and iOS clients.

Push notifications will continue to work for existing users of the app until Sept. 1, 2014. But for new users, it will have been removed when they download the app from the App Store.
You see, Flint for iOS has been made unavailable in the App Store until a new version that removes push notification support is released by Waugh.
When it returns, Flint for iOS will be available in the App Store for $3.99, down from its regular price of $7.99.
Flint for Mac remains available in the Mac App Store. Likewise, its price has been reduced, from $14.99 to $7.99.
Flint for iOS was released last September, nearly two years after the launch of Flint for Mac. It was hailed as an AppAdvice App of the Week.
